Kulturnotiz

German writing joins clauses far more freely than English does — a single German sentence often carries two or three linked ideas where English would use full stops. That is why German prose looks long: it is not verbosity, it is a different tolerance for sentence length. Getting comfortable with und, aber and denn is the first step to reading a German newspaper without running out of breath.

Common questions

+Do these conjunctions change the word order?

No — und, aber, oder, denn and sondern leave both clauses exactly as they were. Only the subordinating group (weil, dass, wenn, obwohl) sends the verb to the end.

+What is the difference between denn and weil?

Meaning: none, both are "because". Grammar: denn leaves the verb in position two, weil sends it to the end. Ich bleibe, denn ich bin müde / Ich bleibe, weil ich müde bin.

+When do I use sondern instead of aber?

Only after a negative, when you are replacing what was denied: nicht X, sondern Y. For an ordinary contrast — "expensive but good" — use aber.

+Is denn the same as dann?

No. Denn is "because" (a reason); dann is "then" (a sequence). They are one letter apart and constantly confused.
